What is the Staten Island/Greenwood sub-load pocket?

The Staten Island/Greenwood sub-load pocket is an area of Brooklyn and Staten Island that represents a constrained area in the New York City transmission system. Much of the generation capacity that supplies Brooklyn on a daily basis is located outside the Borough (i.e. New Jersey and other parts of New York) and flows through interconnections across Staten Island or directly into Brooklyn. When those transmission lines are carrying a very heavy electric load it is not possible to supply all local needs from remote areas. During those times, much of Southwest Brooklyn relies on generation capacity on the Brooklyn Waterfront.
